Authorities are investigating a shooting in which a man wearing a bulletproof vest was shot multiple times at an acquaintance's home, the Anderson County Coroner's Office said Tuesday.

Jeremy Burns, 24, of Anderson, was shot approximately four times, including a fatal wound to the neck, Deputy Coroner Josh Shore said. The shooting happened shortly after 7 p.m. Monday at a home on Oliver Street.

The homeowner took responsibility for the shooting, according to an incident report, although the circumstances surrounding the shooting are unclear. Officers arrived at the scene and made contact with three people, an incident report states. Burns was found in the living room area and pronounced dead at the scene.

No one has been charged or arrested in the case, Lt. Sheila Cole said. The homeowner did not sustain any injuries, Cole said.

The Sheriff's Office continues to investigate the circumstances surrounding his death, Cole said. The Coroner's Office has ruled the shooting a homicide.

"We have not determined at this point whether it was a justifiable homicide," Cole said.

Authorities said they do not know why Burns was wearing a bulletproof vest.
